V HENRY G. VOIGI-I'l, OF NEW BRITAIN, CONNECTICU T, ASSIGNOR TO- SARGENT & i

GOMPANY, OF NEW HAVEN, CONNEC CUT.

To all whom it may concern: .Be it known that I, HENRY G. VOIGH'I', of

State of Connecticut, have invented certain new and useful Improvements in Door- Straps, of which the following is a full, clear,

exact description.

Th s invention relates to door stops, and

it has particular reference to devices of this classhaving means connecting the door with the door casing in such a manner that when the door is opened to a predetermined, but

regulable degree, the opening movement will not only be arrested, but the door will be 15,

held fixed in the open position.

One of the primary objects of the inven-' tion is to furnish a door stop of the general 1. character indicated which is applicable,

.f without ad] ustment, either to a right hand door or to a left hand door. My improved door stop is especially designed for associa- .tion with a combined door check and closer, and as itis double acting so as to be applicable to doors of'either hand, it may be used withsatisfaction on any preferred kind of double actingdoor' check and closer, thereby V imparting to the latter an added and very i jecting end of a pin 15 rigidly secured in the desirable function.

A further object ofthe invention is to pro-v vide a very reliable,. eliicient door stop which can be readily and cheaply manufactured and assembled,-and which is not liable to get out of order. To these and other ends, the invention con- .sistsfin the novel features and combinations of parts to be hereinafter described and claimed. 5

' formed upon the head 4. These cooperating ribs or circular rabbets form bearings upon V by the stop mechanism'hereinafter described. The heads 3 and 4 are held in their pivoted relation against separation by a bolt 7 mounted in the head 4 concentric with its rib 6 and extending through an opening 8 formed at the center of the head 3. The threaded end of the bolt 7 may be provided with a nut 9 which contacts with the outer face of the head 3. This nut 9 is convenientlv locked in place, by a lock nut 10.

The mechanism so far described is disclosed and claimed in my Patent No. 1,296,240, granted March 4, 1919, and is therefore not claimed in this application.

The stop mechanism for the cooperating arms consists 'of a round boss or lug 11 mounted eccentrically upon, and rigidlysecuredto, the head 4 by any desired securing means suchas pins 12. Rotatably mounted upon the eccentric boss 11 is a collar 13.

.This collar 13 is provided with a notch 14,

which notch is adapted to receive the prohead 3. The notch 14 and cooperating pin 15 provide means by which a rotation of the head 3 will rotate the collar 13 upon boss 11. Mounted upon the head 3 diametrically opposite the projecting arm 1 is a threaded boss 16 in which is mounted an adjustable stop screw'17, having a knurled head 18 by which the screw may be rotated.

Theoperation of my device is as follows: Since the collar 13 is rotatably mounted on the eccentric boss 11, which boss is rigidly secured to the head 4, and this collar is nonrotatably connected to the head 3, any relative angular movement of the arms 1 and 2 not only as means for limiting the extent to which the door on which it is placed may be opened, but serves also as a means for holding the door in its open position.

By providing the eccentric boss with the collar 13 instead of increasing the diameter of the boss to that of the outer diameter of the collar 13, and by non-rotatably securing thecollar 13 to the head 3, I am able to obtain stopping engagement between the end of the stop screw 17 and the outer surface of the collar 13 without any relative rotation between these two elements. If the collar 13 should be omitted, itwould be impossible to obtain stopping engagement between the eccentric boss 11 and the end of the screw 17 without a relative rotation between these two elements, which rotation is undesirable in that it would injure the outer surface of the eccentric boss-11.

Should the means which I have provided for preventing relative rotation between the collar 13 and the adjustable stop 17 be omitted, my door stop would still perform its intended function of limiting the extent to which the door upon which it is mounted may be opened, and of holding the door in its opened position, operate less satisfactorily than, it would if the collar is prevented from rotating relatively to the stop 17, for when the collar is prevented from rotating relatively to the,

stop '17 it is moved radially toward this stop by the eccentric boss 11 to abut squarely against the end of the screw 17 so that there will be practically no tendency for the screw to mar or injure the outer face of the collar,

pivoted relation, an eccentric member non-' but if relative rotation between the screw and collar is not prevented the screw will not, abut firmly against the. collar but an edge of the screw adjacent the abutting face of the same will tendto dig into or damage the outer face of the collar.

Various changes may be made in the details, of the construction without departing from the scope of the invention as defined in the claims.

What I claim is:

1. In a stop device, a pair of pivoted arms movable angularly with respectto each other, means for retaining said arms in rotatably secured to one of said arms adjacent its pivot, a stop mounted on the other arm, a collar rotatably mounted on said eccentric member and movable thereby into stopping engagement with said stop by a relative movement of said arms.

2. In a stop device, a pair of pivoted arms movable angularly with respect to each other, means for retaining said arms in pivoted relation, an eccentric member rigidly secured to one of said arms adjacent its pivot, a stop on the other arm, a stop-engagmg member rotatably mounted on said ecbut the device would centric member and movable thereby into and out of locking engagement with said stop by .a relative movement of said arms.

3. In a stop device, a pair of pivoted arms movable angularly with respect to each other, means for retaining said arms in pivoted relation, an eccentric member rigidly secured to one of said arms adjacent its pivot, a stop mounted on the other arm, a collar mounted on said eccentric member and provided with means to prevent relative rotation between it and the second mentioned arm, the collar being moved into locking engagement with said stop by a relative movement of said arms.

4. In a'stop device, a pair of pivoted arms movable ang'ularly with respect to each other, means for retaining said arms in pivoted relation, an eccentric member nonrotatably secured to one of said arms adjaconnected to the arm carryingv the stop and rotatably mounted on said eccentric member and movable thereby into engagement with said stop when the arms are moved relative to each other, whereby the arms are positively locked against further movement in one direction and frictionally locked against movement in theopposite direction.

5. In a stop device, a pair of pivotally mounted arms, a cam member rigidly secured to one arm adjacent its pivot,'a collar rotatably mounted on said member, a stop mounted on the other arm' and means for preventing said collar from rotating relatively to the arm carrying the stop whereby when said arms are rotated the collar is moved into locking engagement with the stop to positively lock the arms against further movement in one directionand frictionally lock them against movement in the opposite direction. 7

6.
